Java Installation Process

Here is the step-by-step process for installing the Java JDK on your computer:

  • Go to the Oracle website and download the Java JDK installer. Make sure you download the appropriate version for your operating system.
  • Double-click on the downloaded file to start the installation process.
  • Follow the on-screen instructions to complete the installation process. You will need to accept the license agreement, choose the installation directory, and select the components you want to install.
  • Once the installation is complete, you need to set the environment variables to point to the JDK installation directory. This step is necessary so that your computer can find the Java executables and libraries. Here's how to do it On Windows:
  • Open the Control Panel and go to System > Advanced system settings.
  • Click on the "Environment Variables" button.
  • Under "System Variables", click "New" and create a new variable called "JAVA_HOME" with the path to the JDK installation directory as its value (e.g., C:\Program Files\Java\jdk1.8.0_211).
  • Edit the "Path" variable and append the path to the "bin" directory inside the JDK installation directory (e.g., %JAVA_HOME%\bin).
  • Verify the installation by opening a new terminal window and typing "java -version". This should display the version of the installed JDK.
